Abstract

L'invention concerne un dispositif de fiche électrique (100) et une automobile électrique. Le dispositif de fiche électrique (100) comprend un composant de douille (300) et un composant de ferrule (200); le composant de ferrule (200) comprend une première ferrule (201) et une seconde ferrule (202) gainée sur la périphérie de la première ferrule (201); et le composant de douille (300) comprend une première douille (301) et une seconde douille (302) gainée sur la périphérie de la première douille (301); la première ferrule (201) est enfichée et ajustée sur la première douille (301) de manière amovible, et la seconde ferrule (202) est enfichée et montée sur la seconde douille (302) de manière détachable; et un contact est formé entre la première ferrule (201) et la première douille (301) et entre la seconde ferrule (202) et la seconde douille au moyen d'une surface bombée élastique, respectivement. La zone de contact efficace du dispositif de fiche électrique (100) augmente, ce qui permet d'obtenir une charge de courant importante et un enfichage rapide, facilitant le remplacement rapide d'un bloc-batterie pour une automobile électrique.
